Review on Klein Tools 31940 2 Inch Bi Metal by Rud Starks

I bought this because it was about 2/3 the cost of other hole saws. I should have known better. It says "optimized for metal" when it should be "only for metal". You will break your hand if you try to use it on wood as the teeth are too aggressive. I ended up spinning back and burning through the wood after nearly breaking my wrist. Back and forth on my switch to a Dewalt hole saw.
